FEED-REGULATOR `FOR GRINDING-MILLS.

SPECIFICATION forming part of Letters Patent No. 252,211, dated January10, 1882. Application ined Nvember4,1esi. (No model.)

To all fac-hom it muy concern:

Be it known thatwe, GILBERT S. GRAVES,

ofthe city of Buffalo, in the county of Erie and State of NewYork, andJACOB HEEDE, of

Peoria, in the State of Illinois, have invented` new and usefulImprovements in Feed-Regulators for GrindingMills, of which thefollowing is a specification.

This inventionrelates more particularly to horizontal-diskgrinding-mills which are employed for grinding grain, together with astream of water in manufacturing starch. The grain which is fed into theeye of the ruimingstone in this manufacture is more or less soft andadhesive, by reason of a previous soaking, and is very apt to clog upthe eye ofthe running-stone, and thereby interfere with a steady anduniform feed., v

The object of our invention is to avoidthis difficulty; and it consistsof a distributing p mechanism arranged in the eye of the runningstone,whereby the material is fed between the grinding-surfaces uniformly andwithout interruption, as hereinafter fully set forth. y

In the accompanying drawings, Figure l represents a vertical section ofa pair of millstones provided with our improvements. Fig. 2 is asectional view of the distributing mech'- anism and the adjacent partsof the millstones,

on an enlarged scale, at right angles to Fig. 1.-

Figs. 3' and 4 are elevations at right angles to each other, and Figfatop plan view of the distributing-spouts; and Fig. Gis a perspectiveview of the guard-rin g applied tothe bed-stone.

Like letters ot" reference refer to like parts in the several figures.

A represents the stationary frame ofthe mill; B, the bed-stone, G, thebushing thereof; D, the mill-spindle; E, the bail; F, the runningstone;F', the eye thereof, and G the curb, all of ordinary and well-knownconstruction.

Hrepresents the distributing-spout,arranged in the eye F oftherunning-stone, and secured to the bail E, so as to revolve therewith. As

shown in the drawings, the distributing-spout is provided with two legsor discharge nozzles, H', arranged diametrically opposite each other,and extending downward to within a shortdis-` tance of the top of thebed-stone. The lower ends of the nozzles 4 H are cut off obliquely,

their forward edge being the deepest, and the bottom of the nozzlerising rearwardly, as indicated by the arrows in'Fig. 4.-

I represents the adjustable feed-tube, of ordinary construction,depending into the upper portion of the distributing-spout H, and'K isthe revolving saucer or concave plate, arranged on the bail underneaththe feed-tube, for distributin g and delivering the material from thefeedtube I into the feedspout H. i is the water-pipe, through which astream of water is conducted to the saucer K. The saucer "K is providedon its under side with a screw, k,

' which penetrates the saddle or bottom of the distributing-spout H atthe junction ofthe nozzles H', and which tapsinto the bail E,wbere byboth thesaucer and the distributing-spout are rmly secured to the bail.L represents the guard-rin g arranged on the upper side of the bed-stoneB,within the lower enlarged portion ofthe eye of the runner, and outsideof the lower ends of the nozzles H'. The ring L is secured to thebushing() ofthe bedstone B by angle-bars l, whichl overlap the bushing,and are secured thereto by screws or other suitable means.

m represents perforations formed in the lower portion of the ring L forthe purpose of permitting the water to escape therefrom.

The grain is fedv into the feed-tube I, and a stream of water throughthe pipe t' in any well! known and suitable manner, and passes into therevolving saucer K, by which the material is delivered into thedistributing-spout H, from which it escapes through the nozzles H intothe annular space within the ring L, wherein it accumulates untilit isremoved by the revolving nozzles. The depressed front edges of thenozzles force the material outward over the-upper edge of the ring L andagainst the lower face ofthe running-stone F, and the latter then seizesthe material and forces it outward between the grinding-faces in aWell-known manner. As the depressed front edges ofthe nozzles H removethe material from withnthe IOO zov

Arangement of tuo nozzles, as shown in the water from the space Withinthe ring, and prevent the Water from accumulating therein andinterfering with the proper discharge ofthe material from the nozzles.The ring. L also servestoiniercept heavy metallic substancessuch asnails, screws, and metallic fragments-n which may be contained in thegrain, as these substances tend by gravity to Work to the bottom ofthelayerot'material within the ring and accumulate within the same, and aremoved inward toward the spindle by the oblong shape of the nozzles.These metallic particles are readily removed from time to time, and inthis manner prevented from injuring the grindingfaces ofthe stones.

Itis obvious that only one nozzle H may be employed, if desired; but Weprefer the ardrawings.

We claim as our inventionl. The combination, with the running-stone F,provided with arevolvin g distributing-spout H, having one or moredischarge-nozzles, Hf, arranged in the eye ofthe runner, .ofthe bedstoneB, provided with a guard-ring, L, substantially asset forth.

2. The combination, with the running-stone F, provided witharevolvingdistributin g-spout, H, having one or more discharge-nozzles,H', arranged in the eye of the runner, of the bedstone B, provided witha guard-ring, L, having perforations m, substantially as set forth.
